Flying with Small Dogs in the Cabin: Which Airlines Allow It and the Rules You Need to Know
Travelling with a small dog in the cabin is a real option on many international routes - it avoids the hold, keeps the dog with you, and is generally less stressful for both animal and owner. But the rules are strict, vary by airline, and catching the wrong one can result in your dog being rejected at check-in.
The In-Cabin Weight Rule
The universal constant: the combined weight of dog and carrier must be under the airline’s limit. Most carriers set this at 8 kg. Some allow up to 10 kg. A few budget carriers ban cabin pets entirely.
Weigh your dog in its actual travel carrier before booking - not estimated weight, actual combined weight. Airlines weigh at check-in. Exceeding the limit means the dog must travel as checked cargo, which may not be possible on the same flight.
Carrier Dimensions
The carrier must fit under the seat in front of you. Airlines specify maximum dimensions, typically around 55 x 35 x 25 cm though this varies. Buy the carrier before booking and check it against your specific airline’s published dimensions.
The dog must be able to stand, turn around, and lie down in the carrier.

Booking the Cabin Pet Spot
Cabin pet spots are limited - often 1-2 per flight. Book as early as possible and confirm the cabin pet reservation when you receive your booking confirmation. Some airlines do not allow you to book cabin pets online and require a phone call.
During the Flight
The dog must stay in the carrier, under the seat, for the entire flight. Taking the dog out is not permitted. Most dogs settle after takeoff if they’ve been crate-trained. A worn item of your clothing in the carrier helps.
Documentation Reminder
Health documentation applies regardless of cabin vs. cargo. Check your destination’s specific requirements.
